VENTILATING DEVICE FOR TOILETS.

Application filed October 13, 1926. Serial No. 141,298.

suction machine is used, usually located in the basement to which pipes lead from each floor or" the building, for sweeping and other purposes, and therefore the object of the present invention is the provision of a ventilating device of the character above stated which may be used in connection with such suction machine,

lVith the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views, I

Fig. 1 is a side elevational view of the toilet bowl with the cooperating parts of the ventilating device in their inoperative condition;

Fig. 2 is a .side view partly in section and,

partly in elevation, of the bowl and the ventilating device while the latter is in operative position;

Fig. 3 is the top view, partly in elevation and partly in sect-ion of the valve mechanism forming part of the ventilating device; and

Fig. 4 is a side view, partly in elevation and partly in section of the valve mechanism constituting a part of the ventilating device.

The ventilating device cooperating with the. toilet bowl 110 embodies a cup-shaped casing 11 having an integrally formed pipe 12. By means of flange 13 and screws 14 said casing is attached to the wall 15. Pipe 16 leads to the suction machine which is not shown in the drawings, is receivable through wall 15 within cup-shaped casing 11 andpipe 12. Section of pipe 16 closely fits within said pipe 12so as to provide air-tight connection between the two pipes. Section of pipe 16 which remains within cup-shaped casing 11 is provided with a valve casing 17 and valve stem 18. On linewith said valve stem 18 opening 19 is provided in the cup shaped casing 11. Cover 20 normally maintains said opening closed. Said opening provides access to valve stem 18 for the purpose of opening or shutting off the valve in pipe 16 for either permitting or shutting oil the action of the suction machine upon the ventilating device. Pipe 12 on the lower portion of its periphery is provided with a threaded opening 21 for receiving the end of pipe 22 which leads to the toilet bowl 10. The other end of said pipe 22 remains within bowl 10 and is covered with a mesh '23 for preventing splashes of water to enter said pipe.

The invention further embodies a substantially cubic block 24 which is positioned on line with pipe12. Two parallel side plates 25 and 26 mounted at the end of pipe 12 by screws 27 and 28, respectively, maintain said block 24in operative position in'respect 01 pipe 12, said plates 25 and 26 being secured to said block 24 by means of screws 29 and 30, respectively.

Valve rod 31 is receivable by one of its ends within the enlarged mouth of pipe 12, the movement of said valve rod 31 within said pipe 12 being limited by shoulder 32 formed within said pipe 12, while the other outer end 01"" valve rod 31 is receivable within bore 33 made in the cubic block 24. Substantially at the central portion of said valve rod 31 and at two diametrically opposite points on its periphery onhorizontal line,

said valve rod 31 is provided with two pins 34 and 35 providing bearings for washers 36 and 37. Positioned upon said valve rod 31 at the point adjacent the end of pipe 12 is collar38, which at its outer end is provided with an outwardly projecting flange 39. Interposed between the inner end of block 24 and washer 37 is a coil spring 40 encompassing the valve rod 31. Coil spring 41, which,

however, is heavier than spring 40 is posi tioned upon valve rod 31 and remains interposed between washer 36 and flange-39 upon collar 38.

The outer ends of plates 25 and 26 carry hereinafter stated.

Collar 38 has two outwardly projecting pins'50 and 51 for pivoting thereupon the upper ends of L-shaped plates 52 and 53, respectively. The lower horizontal portions of said plates 51 and 52 converge toward each other and receive therebetween arm 54: wherein it is held in rigid condition by means of bolts and nuts 55. The outer end of said arm 54 has a U-shaped plate 56 pivoted thereto by its ends upon pin ceives the end of rod 58. The ad acent end of said rod 58 is threaded for receiving -thereupon nut 59 which remains within said U-shaped plate 56. By means of said nut 59 the length of rod 58 may be regulated as is required for the operativeness of the device. The outer end of'rod 58 has chain 60 attached thereto, while the other end or said chain 60 is attached to the upper end of a substantially L-sliaped bar 61. The footportion of said L-shaped bar 61 is tastened to the lower face of seat 62 near the point at which said seat ishinged to the bowl 10.

The operation of said U-shaped locking plate 42 is had through the medium of rod 63 which is receivable within collar 48 wherein it is adapted for longitudinal slidraised as will behereinatter described. The

outer end or" said rod 63 is provided with. nut

65, and interposed between said nut 65 and collar 48 is a coil spring 66 for the purposes hereinafter stated. The other end of said rod63 is pivoted to L-shaped bar 67 on pin 68. The foot portion of said L-shaped bar 67 is attached to thelower face of the cover 69 near to the point where said cover 69 is hingedly' connected to seat 62.

The suction machine hereinabove mentioned at all times maintains a vacuum in pipe '12 when valve 18 remains open. The action of said suction machine is communicated to bowl 10 by means of 'pipe 22 through which foul air from bowl 10 is passed to suction machine. Rod 31 acts as a valve for either opening or closing the communication 21 with pipe 12. When seat 62 remains'in an unoccupiedposit-ion illustrated by dotted lines on Fig; 2 spring 40 re mains expanded pressing valve rod 31 toward shoulder 32, thus keeping the inlet 21 of pipe 22 closed and out of ceinmunication with pipe 16 of the above mentioned suction machine. As soon as the seat by virtue of its occupancy is pressed downwardly toward the upper edge of bowl 10, the position illustratedby full lines on Fig. 2, plates 52 and 53 are caused to exert compression of spring 40, causing its contraction, it being observed that spring 41 by virtue of its being heavier than spring 40 remains unaiiected by the action of said plates 52 and 53 and the compression oi sprmg 40. Thus, due to the shifting action and pressure of said'plates 52 and upon flange 39, spring 41, washer 36 and'pins 34 and 35, valve rod 31 is caused to slide in the reverse direction for opening vent '21 or pipe 22. lVhen said seat 62 remains in con-- tract with the bowl 10 and is occupied. cover The bent portion of the U-shaped plate 56 re- 69'is of course open,the position illustrated on Fig. 2, and by means of L-shapedbar o1,

'31 within block 24 by virtue of the action of plates 52 and hereinabove described.

It will therefore be seen that when cover 69 is opened and seat 62'is occupied, position illustrated in full lines on Fig. 2, locking plate 42 will remain tilted permitting sliding movementof valve rod 31'ior opening vent 21 of pipe 22. On releasing seat 62 from contact with the edge of bowi 1 spring 40 is sutlicie'ntly strong due to its expanding action and consequent pressure upon pins 34 and 35 not only to force the inner end of valve rod 31 toward shoulder 32 for closing vent 21 of pipe 22 but also tomaintain said seat 62 in tilted position'illustrated by dotted lines on As hereinabove stated cover 69 through L-shaped bar 67, rod 63, nut 64 and spring 66 is adapted for operating U-shaped locking plate42. 'lVhen said cover 69 remains open bar 67 exerts a backward pressure upon rod-63 which in turn through nut 64 exerts rearward pressure upon collar 48 causing rearward tilting of extension 47 and consequent uppershitting movement of the central portion of plate 42 bringing the same out 01 contactwith-the outer end of block 24, thus permitting the unobstructing slid ing movement of valve rod 31 within said block. When said cover 69 remains in open position illustrated on Fig. 2, and plate 42 remains in consequence in upper tilted position, spring 66 is expanded. When said cover 69 shallbe brought downwardly to tilted position to correspond with the position of seat 62, the position illustrated by dotted lines on Fig. 2, L-shaped bar 67 will be shifted upwardly to the position substantially corresponding with the position of bar 61, rod 63 will be retracted together with nut 64 from collar 48, and spring 66 will then be caused to contract and exert pressure upon the adjacent end of said collar 48 causing plate 42 to drop down an lock the outer end of block 24. r

From the hereinabove made description it will be apparent that when said seat 62 and cover 69 remain in tilted position locking plate 42 will cooperate with the outer end of block 24 for preventing the outward shitting movement of valve rod 31. In that latter position of seat 62 and cover'69 plates 52 and 53 will remain in theposition illus trated by dotted lines on Fig. 2, that is in abutment with the outer end of pipe 12, by virtue of the expanding action of springs and 41. I

Then seat 62 and cover 69 are pressed downwardly upon the bowl 10, position illustrated on Fig. 1, the position of locking plate 42 will remain unaltered i'rom theposition described in the last preceding paragaph. By bringing said cover 69 to the posit-ion shown on F 1 rod 63 will become further retracted bringing nut 64 farther away from collar '48, and consequently spring 66 will become more contracted.

When said seat 62 remains in closed position illustrated on Fig. 1 the action of plates 52 and 53 upon rod 31 through springs 40 and 41 will not affect rod 31, owing to the fact that locking plate 42 prevents the shifting of said rod. From the drawings and herein made description it will be apparent that when seat 62 and cover 69 remain in closed position illustrated on Fig. 1 the consequent pulling action of plates .52 and 53 will merely compress spring 41 without atfecting the position of valve rod 31 illustrated on Fig. 3.

From the Various cooperating positions of seat 62 and cover 69 hereinabove described 1t may be briefly stated that when said seat remains in occupied posit on illustrated on Fig. 2 and cover 69 remains in open position, the valve rod 31 will become retracted from within pipe 12 so as to open vent 21 and provide the communication thereof with pipes 12 and 16, thus to cause the operation 01 suction to exert its influence upon bowl 10 through pipe 22. When seat 62 and cover 69 remain in tilted position illustrated by dotted lines on Fig. 2, valve rod 31 will remain within pipe 12 by virtue of expanding action or spring 40. When in that latter position of seat 62 springs 40 and 41 are sufiiciently strong to hold plates 52 and 53 in retracted position, positionv shown by dotted lines on Fi 2, and maintain said seat 62 and cover 69 in tilted position. It is therefore apparent that when said seat 62 and cover 69 remain in said last mentioned tilted position communication of pipe pressed toward bowl 10, the common posi tion of said cover when the occupant uses the bowl for dressing purposes, the valve rod 31 will remain in abutment with shoulder 32 for closing vent 21. In that latter position of said seat 62 and cover 69 locking plate 42 will remain in abutment with the outer end of block 24 preventing the outonly when seat 62 is occupied and cover 69 is raised.

lVhile there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope'oi the invention as claimed. 7
